IN FERROUS METALLURGY: Having completed the gasification of its production plants, Jelen Do can now offer a new product - metallurgy lime adapted for use in different phases of steel production (in desulphurization and refinement, as a melting agent) for three basic purposes: 1. Production of crude cast iron from iron ore. 2. As a melting agent in blast-furnaces and converters, where, reacting with SiO2, phosphorus, sulfur and, to a lesser extent, manganese, it removes these contaminants from steel; the by-product of the process is slag, which can be removed. 3. in secondary refinement of steel and in manufacturing of steel products. The lime from our quarries has very little admixtures that have adverse effect on the quality of steel (alkalis, sulfates,...) and gas-fired calcination eliminates the possibility of admixtures of sulfur occurring in lime.

IN CONSTRUCTION INDUSTRY: Lump lime is used for making of slaked lime, which is then used as a binder in making of mortar. GROUND AND MICRONIZED LIME Unslaked ground lime is used for removal of silicates from bauxite ore in production of alumina, from which aluminum is then extracted. Unslaked micronized lime is used as a raw material for production of aerated concrete and silica brick.
